Hi, I have a 3 nodes cluster, each with less than 200 GB data. Currently all nodes have the default 256 value for num_tokens. My colleague told me that with the data size I have (less than 200 GB on each node), I should change num_tokens to something like 32 to get better performance, especially speed up the repair time. Do any of you guys have experience on this? I am running Cassandra Community version 2.0.9. The cluster resides in AWS. All keyspaces have RC 3.
Thanks. George.
